For doubleclick it is best to use their HTML5 templates.

Everything goes in one folder, including images and only include the JS files that you are using, plus only one html file. They also require a jpg backup and there is also the option of adding a flash backup too.
I gave them one index.html, one css file, the main js file, TimelineLite.js, TweenLite.js and CSSPlugin.js, plus all the png image files. If it's a heavy load, they will tell you to use polite load, which is easy enough, because there is a template for that as well. Hope this helps.
